Just consider the Group they come from in your search. Terriers will be boisterous, active and the will bark and undoubtedly they will dig up your garden etc. Their very name means 'to go to ground'
Most terriers, not all of course require diligent grooming.
Toy breeds can have their health problem, so be sure and go to a reputable breeder.
Pra, cataracts, slipping patellas, to name a few. They are so popular that most people don't care about the health checks.
Make a list of things that are important to you - barking, hyperactivity, shedding, grooming. If you like hiking, make sure you get a dog that can keep up. A brachcephalic type would probably not do for you in that instance.
Whippets are gorgeous, but being in the hound group, they would have to be watched closely off leash. Plus, they can be very aloof, especailly around strangers. My friend owns several and she loves that about them, but they are difficult to train, as they live to please themselves.
Ahh dogs, I love them all and wish I had the time and space to own one of each.
